1st Arecibo Survey


The 1st Arecibo Survey (ar1) published its results in 1974 and 1975 with a total of 40 new pulsars discovered. It detected a grand total of 9 pulsars. The fastest pulsar discovered was J1915+1606 with a period of 59.03 milliseconds and the slowest pulsar was J1944+1755 with a period of 1.9969 seconds. The smallest pulsar dispersion measure was J1918+1444 with a DM of 27.202 pc/cc and the largest pulsar dispersion measure was J1926+1928 with a DM of 445.0 pc/cc. There were a total of 105 pulsars known before the first discovery was published. This survey increased the total amount of known pulsars by 38.0%.

There were 3 papers written about the discoveries of this survey: A High-Sensitivity Pulsar Survey, Discovery of a pulsar in a binary system, A Deep sample of new pulsars and their spatial extent in the Galaxy.
